This section describes the features which make up OS MasterMap Highways Network - Routing and Asset Management rights and restrictions. The attributes associated with these feature types are listed below along with a brief description of their data properties.
The name of the attribute and what it is describing.
The nature of the attribute, for example a numeric value or a code list value.
The length of the attribute provided (optional).
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory within the product. These are denoted by:
‘1’ – there must be a value.
‘0..1’ – population is optional but a maximum of one attribute will be returned These values may be used in combination.
The Rights and Restrictions sub-theme includes properties that prohibit, restrict or regulate the use of the network by traffic. Rights and Restrictions are typically defined through legislation, including the Traffic Regulation Order (TRO) made under the Road Traffic Regulation Act 1984.
The following types of rights and restrictions are in the scope of the current product:
Access Restrictions
Turn Restrictions
Restrictions For Vehicles (Height, Weight, Width and Length restrictions)
Highways Dedications (indications of Rights of Way)
Rights and Restrictions features record the effect and nature of the real-world restriction or environmental factors. However, this is not always possible as restrictions may manifest in many different ways yet have the same effect.
For example, a single restriction may consist of a one-way street that has a no entry sign, no right/left turn sign and/or mandatory turn signs on the approach roads. This is represented in the simplest way by recording a one-way street. To ensure a level of consistency, a hierarchy is used when more than one restriction that has the same effect occurs at a given location. Only the restriction that has the highest priority will be captured.
| Priority | Restriction |
|---|---|
Therefore, Rights and Restrictions primarily model the effect of any restriction in the simplest possible way and secondary to this is recording the real-world manifestation.
Highway dedication indicates which types of user have access to the given section of the Highway.
Against every section of geometry supplied by the local highway authority, there will be one of eight different types of Highway Dedication defined in the Highways Act 1980 and the Countryside and Rights of Way Act 2000 which determines the Highway user access.
There can only be one Highway Dedication type applied to the geometry at any given date or time. It is likely that more than one Highway Dedication type applies to a section of Highway (i.e. a highway open to all vehicles will also have pedestrian way or footway access). The following table gives the order of priority where the highway dedications under each is inferred:
| Priority | Highway Dedication |
|---|---|
*Motorways and Cycle Tracks (not Cycle Ways) impose restrictions on all other Highway users.
The Highway Dedication also identifies if the feature forms part of a National Cycle Route, Public Right of Way, Quiet Route, or Physical Obstruction, or if a Planning Order or Vehicular Traffic order exists.
The Highway dedication value is only an inference of where a Public Right of Way exists and therefore not the definitive record of Public Rights of Way; that is in the definitive map held by the relevant authority.
A Highway Dedication feature will reference back to the Path Network through Network Reference and will reference a RoadLink or Street Feature.
The Highway dedication feature type is not extended to Scotland because this information does not exist in the source local authority data.
Definition of which type of Highway user has access to a particular section of the Highway.

A turn restriction is a restriction based upon a vehicle manoeuvre. This type of restriction includes prohibitive driving instructions, mandatory driving instructions and implicit restrictions. Prohibited instructions are indicated by road signs within a red circle, examples include No U Turn, No Right Turn or No Left Turn. These can include exceptions to the instruction and are typically elements like Except for Buses. Mandatory driving instructions are indicated by road signs within a blue circle or painted on the roadway such as Turn Right, Ahead Only and No Left Turn. Implicit restrictions occur where a turn is not signed as prohibited but would not be a normal manoeuvre. For example, where a road splits around a traffic island or at complex junctions where additional geometry has been captured to reflect the traffic flow. These are not differentiated from actual signed restrictions.
A Turn Restriction will reference back to the Roads product through Link References and Multiple Link References.

RestrictionForVehicles are constraints that apply to the vehicles based on their physical characteristics: height, weight, width and length. These are required to protect structures such as bridges and tunnels from damage, or to restrict/prohibit use by vehicles that exceed specific dimensions, usually for environmental reasons.
RestrictionForVehicles has been extended to support the full definition of height, weight, width and length restrictions as defined in the UK to ensure that they can:
Apply to specific vehicle types only.
Relate to a structure for which the restriction is designed to protect (for example, a Bridge).
A RestrictionForVehicles will reference back to the Roads product through either a Node Reference or a Point Reference.
The context diagram below shows how the RestrictionForVehicles has been inherited from INSPIRE and the attribution held on a feature.
Height, Weight, Width and Length restrictions (HWWL) for vehicles. Measure shall be defined in metric units for width, height and length restrictions. For all weight restrictions, measure will be defined in tonnes and measure2 will not be supplied.

Access to a road or area by vehicles can be legally prohibited. Prohibited access restrictions are indicated by regulatory signs with a red circle or a no entry sign. In addition, access could be limited for use by particular classes of vehicle, these are indicated by regulatory signs with a blue circle. Access restrictions may also include exemptions to the restriction. The Access Restriction feature type comprises of these types of restrictions.
An Access Restriction will reference back to the Roads Product Network through Point Referencing.
